Long, unbroken pages of text show authority and draw the reader into the writing

As a writer and reader I disagree with this. Perhaps if you are writing for a scientific journal or business report, long blocks of text can seem like you have a lot of info. Generally speaking, especially in fiction and non fiction i think unbroken pages of text will best case scenario bore a reader, worst case scenraio burden and overwhelm  them with a lot of info so the feel daunted about continuing.
